 Critics have particularly praised the noble arias Haydn writes for his serious characters Flaminia and Ernesto and the evocative music for the flight to the moon in act 1.Several numbers (vocal and instrumental) combine triple metre and a slow to moderato tempo.Flaminia's act 1 "Ragion nell'alma siede" has the typical form and coloratura of opera seria, while Lisetta's "Se lo comanda" in act 2 mixes comic and serious styles.
